摘要： A femtocell increases efficiency and coverage of a macrocellular network operating in a co-channel manner within the macrocell spectrum by selecting subcarriers for its mobile station using both the subcarrier allocation map received from the macrocell and a spectrum sensing operation. Interference is avoided by selecting only subcarriers not allocated by the macrocell and subcarriers allocated to users not nearby to the femtocell. Interference is eliminated from the received signals using co-channel interference avoidance techniques. Selection of subcarriers for femtocell use may take into consideration inter-carrier interference detected.

摘要： Methods for increasing power saving in a station that sends or receives frames in an ad hoc wireless network (e.g., IBSS), while allowing the station to enter a power-saving mode quickly upon completion of scheduled tasks. At the same time, a method of the present invention allows two stations in the ad hoc wireless network to infer each other's power management mode without requiring an ATIM/ACK exchange between the STAs within an ATIM window. Consequently, a station may enter a power-saving mode promptly without impairing the station's ability to receive packets. In one embodiment, a "more data" field is used between stations to exchange information. Stations with various computation abilities provide information under different time constraints. The stations may enter power-saving modes that send multicast/broadcast frames or use promiscuous mode within an ATIM window.
摘要翻译：在用于在自组织无线网络（例如，IBSS）中发送或接收帧的站中增加功率节省的方法，同时允许站在完成预定任务时快速进入省电模式。同时，本发明的方法允许自组织无线网络中的两个站点推断彼此的功率管理模式，而不需要ATIM窗口内的STA之间的ATIM / ACK交换。因此，站可以及时进入省电模式，而不会损害电台接收分组的能力。在一个实施例中，在站之间使用“更多数据”字段来交换信息。具有各种计算能力的站点在不同的时间限制下提供信息。这些站可以进入在ATIM窗口内发送组播/广播帧或使用混杂模式的省电模式。

摘要： An apparatus and method proactively managing the load of an 802.11 WLAN based on one or more per-class station counts, in which the stations are classified according to access categories, user priorities, or services. Alternatively, the load of an 802.11 WLAN may also be proactively managed based on provisional or non-provisional per-class traffic specification, depending upon the status of traffic streams. Load balancing may be achieved by (a) collecting per-class station count information, either through an AP, or through exchanges with neighboring APs or wireless stations, and (b) proactively influencing association decisions between wireless stations and APs.

摘要： A method for power saving in an ad hoc wireless computer network determines an optimal ATIM message exchange window. The method (a) determines an effective number of nodes that participate in exchanges of ATIM messages during an ATIM window; (b) using the effective number of nodes, calculating a length for a data frame transmission window; and (c) calculates a length for the ATIM window using the calculated data frame transmission window. In one instance, the method determines the effective number of nodes based on the number of senders of ATIM messages. In another instance, the effective number of nodes is determined based on both senders and recipients of the ATIM messages. The method may determine the effective number of nodes from a number of successful ATIM message transmissions in a given time period. The calculated ATIM window size can be provided as an initial value to other methods that dynamically adjust the ATIM window size.

摘要： Methods are disclosed to support power saving states of a beacon station in an ad hoc wireless local area network (WLAN). Some of the methods allow exchanging power management information among stations in the wireless network and to allow beacon station handovers. In some methods, always-on stations are given a higher priority to become a beacon station or a beacon station handover destination. The methods achieve good power saving while minimizing beacon handover frequency.

摘要： Packet communication method and system in which a packet destined for a terminal is provided service according to a service table indexed by packet classification and the terminal's power mode. The service table may specify for a connection a predetermined quality of service or discarding the packet. For a power mode having an alerting (i.e., paging) mechanism, the service may include alerting the terminal. The service table may also include a network edge point's own service requests and service requests from terminals, provisioning servers, and handoff sources. For a multicast or broadcast packet, as each terminal may be in a different power mode, the associated service in the service table may therefore be different for each terminal. In that case, the packet is provided with service so that any given terminal is provided with at least the quality of service specified in the service table. Thus, a multicast or broadcast packet is discarded when the service specified for all terminals is "discard." Each terminal is alerted, however, if the associated service includes alerting the terminal. During handoff, a part of service table associated with the terminal can be transferred from the handoff source to the handoff destination.
摘要翻译：分组通信方法和系统，其中根据由分组分类索引的服务表和终端的功率模式，向目的地为终端的分组提供服务。服务表可以为连接指定预定的服务质量或丢弃该分组。对于具有警报（即寻呼）机制的电力模式，该服务可以包括提醒终端。服务表还可以包括来自终端，配置服务器和切换源的网络边缘点自己的服务请求和服务请求。对于多播或广播分组，由于每个终端可能处于不同的功率模式，因此对于每个终端，服务表中的相关联的服务可能是不同的。在这种情况下，分组被提供服务，使得给定终端至少提供服务表中规定的服务质量。因此，当为所有终端指定的服务为“丢弃”时，组播或广播分组被丢弃。然而，每个终端被警告，如果相关联的服务包括警告终端。在切换期间，与终端相关联的服务表的一部分可以从切换源传送到切换目的地。

摘要： In a fast active scanning wireless network apparatus and method for quick determination of available access points (20), information about a candidate set of available access points (20) is obtained, and a candidate access point is identified from the candidate set. A mobile station (10) then queries the candidate access point with a probe request that designates the candidate access point as a sole responder. The probe request prevents other access points from contending for the medium of communication between the mobile station and the designated sole responder access point by excluding the attempt by other access points (20) to transmit probe responses. The apparatus and method thus increases the probability of a fast and successful probe request from the mobile station and subsequent response from the designated access point (20). The designated access point may also respond with a probe response of high priority, preventing intervention of communication.
